IMPROVEMENT IN CHURNS.

Specification forming part of Letters Patent No. 117,821, dated August 8, 1871.

To all whom 'it may concern:

Be it known 4that I, J A0013 SHAVER, of Lawrence, in the county ci McHenry and State of Illinois, have invented a new and useful Improvement in Chur-ns, of which the following is a speciiication:

The nature of the present invention consists in the novel construction and arrangement of horizontal dashers, which are operated by a vertical cogged dasher-rod so as to oscillate in a semicircular churn-body or boX, the several parts considered new being hereinaiter fully described and shown.

In the drawing, Fig. 1 is a sectional elevation of my improved churn taken transversely to the dashers; Fig. 2, a plan view of one ofthe dashers removed from the box and drawn double the size oi' the dashers at Fig. 1; Fig. 3, side and edge views oil the cogged dasher-rod, also drawn double the size of Fig. 1; Fig. 4, an elevation of one of the dasher-bearin gs.

A represents one of the ends of the churn-box; B B, the vertical sides; C, the standard; and E, the lever by means of which the dashers are operated. K K are the bent sides of the box, fitted into the vertical sides B B by means of V-sln ped tongues @c x, Fig. 1, and they are also fitted into a bottom piece, J, in the same manner, so that, in case of shrinkage, the joints may be readily calked without splitting the sides of the grooves in the parts B B J, as would be the case were the sides parallel, as is usually the case where the body ofthe churn is made partly of bent stuff. G G represent the rollers of the dashers, which are made of wood, and provided with cogs N and with dashers or wings H. These dashers, as will be seen at Fig. 2, are narrower at their outer ends than where they enter the rollers G G. This construction is necessary, in order that the cream may be forced outwardly against the churn-box, and so that in the last stages of the churning the milk may be readily separated from the butter. The cogged dasher-rod D is pivoted to the lever E in the usual manner, so thatwhen it has given to it a vertical reciprocating motion the wings H will oscillate and come nearly together above and below the rollers G, as shown by dotted lines I, Fig. 1, said rollers turning in bearings P P made in the bracket M. The cogs F of the rod D are cut on the end of the wood separate from the sides T, and then iastenedbetween said sides by means of bolts or otherwise, as more clearly shown at Fig. 3. By this means the cogs are very strong and arernot liable to soon wear out, and when they become worn can be readily removed and replaced by a new one, while the rod remains perfect.

The operation is very simple, requiring only that cream or milk be putin the box and the lever E moved up and down until the desired object is accomplished.

In the foregoing I have described the box inv detail, and also shown the manner of putting the cogs in the rod D F; but I do not claim them as my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

'Ilhe combination of the cogged rod D F, dashers G H, lever E, and box A B K J, as and for the purpose set forth.
